Mark W. demoed
running one of his Mdrive motors from his PC using an improvised
interface. He also showed us how to use a function generator to
generate the step-clock.

Jim demoed an
RS-232 to RS-422 interface to two IMS controllers. The controllers
were connected in a party line arrangement and each had its own 1
character address and would only respond to a command when the
command was prefaced by that address.

Next we had a
talk on coupling a motor to a load.

Duncan talked
about his Arduino theater stage projects. Then he demoed the motors
Mark gave him discussing his unique use of MS Excel as a programming
tool.

Eric
talked about the plan to hold an AVR microcontroller class. The
course will consist of 4 monthly consecutive 2 hr sessions held
during the regular CRS meeting time. The first session will be held
at the February meeting. See Jake's e-mail for instructions on how to
sign-up.

Lastly,
Mark W. talked about the analog voltage anomoly that's plaguing his
AVR project and elicited the group for help.
